SoEW, PoDD, MS, PoFV, and GFW I never even 1cc'd on Hard. But it doesn't really make any sense to go for Hard on them now. I'll just skip to Lunatic.
My early run vids of GFW were from when I didn't realize that shooting charged your freeze meter faster. Should be obvious why I failed so horribly on them.
Still, I guess I could easily take most of these out quickly once I start trying. SoEW, LLS, and MS will be relearning the game, but LLS is easy enough to 1cc, so maybe I'll try to 1cc while playing for using lives and bombs for score instead of survival, and that'd make it a more decent challenge. But I'd need to learn the optimal bombing spots. I don't know if I could even get to Shiki now on PoFV like I used to, but that game is pretty much luck on whether the AI decides to die. GFW shouldn't be that bad if I spam freeze. PoDD is the tough one obviously being the hardest of them all, even harder than UFO.
I don't even know who I should be using for PoDD either. And I never got the final extend on Normal or on my old Hard runs.
